should they have done a 'Renegade' movie for IV?

III was a radical departure from the norm and at the end there were all kinds of possibilities for the next film.... (e.g. Kirk & his crew of renegades in the BOP off the grid on the run making do with what they can salvage Blakes 7 style for 1 or 2 movies before things get sorted out with the UFP...)

It’s a shame we didn’t get a full on ‘renegade’ movie for IV - a more Star Warsy approach to the trekverse , building on Trek III which itself had quite abit of SW influence (cantina scene, alien microbes, opening up the ST universe with more ships/spacestations, the malfunctioning Excelsior/Falcons light speed, crew becoming rebels,Kirks Temple of Doom style fight/Vulcan Temple, plus the story itself mirrored Empire Strikes Back a little)

also it'd been cool to have the Genesis trilogy stretched out to 4 films & the bookend VI TUC (with no standalone Trek V)

alternative Treks 4-6 if theyd gone the Blake 7 route:

Star Trek IV The Dark Frontier</I>. After the successful resurrection of their comrade Captain Spock, the renegade crew of the fallen Enterprise (along with Savvik and Maltz) are forced into exile by a dangerous secret section of Starfleet led by a vengeful agent (Michael Ironside) who wants to retrieve the captured BOP to instigate a war with the Klingon empire, leading to a fierce manhunt across the galaxy.. (cue multiple planet locations, Kirk&Co in Mos Eisley environments, SW type aliens abound, Maltz as Worf type character who dies heroically saving the others, near escapes/shoot outs with  Federation soldiers, Kirk v Ironside debate/end fistfight, BOP v Excelsior climax. Shades of what was to come in TUC and again in STID And to a certain extent Insurrection which sort of attempted a Trek III approach in its 2nd half)

<i>Star Trek V The Voyage Home. After defeating a sinister conspiracy plot in Starfleet, Admiral kirk and his renegade crew finally decide to face the federation. However on the way back to earth a mysterious alien probe begins to disrupt earths defences..

Star Trek VI The Undiscovered Country – Captain Kirk and the crew of the Enterprise A are ordered to oversee a peace treaty with the Klingons...
